To all whom it mayconcem: Be it known that I, ALBERT BECK, a citizen of the United States, and a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Selective Change Maker; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings and to the numerals of reference marked thereon, which form a part ofthis specification.

This invention relates more particularly to an improved typ'e'ofxa selective change maker wherein a plurality of coin tubes are providedfor holding coins of different denominations, each of said tubes having associated with the lower end thereof a leveractuated spring-controlled bell-crank having a spring-controlled ejector supported on one end thereof for the purpose of ejecting a coin from the tube and causingsaid coin I to move rearwardly into discharge position as a member preventing premature discharge of a coin and pivoted on the other end of the bell-crank is retracted to allow the coin to slide into a discharge chute.

It is an object of this inventionto provide a selective change maker wherein a 'lever is provided for the purpose of actuating a spring-controlled bell-crank having pivotally mounted on the l ends thereof coin control members between which a'coin is normally positioned to. permit ejection thereof.

It is also an object of this invention to provide a change maker wherein acoin in a coin tube is normally positioned between oppositely disposed control members, one of which normally acts to retain the coin in place until the ejecting member is actuated by a lever'controlled pivoted means which simultaneously retracts the retaining mem-v ber as it advances the ejecting member to cause discharge of the coin.

Another object of, the invention is to pro. vi'de a change maker having means on a coin retaining member for preventing a coin improperly deposited into a coin tube from dropplng through a coin tube base slot when a coin ejector is in normal position.

It is a further object of the invention to provide a change maker wherein a lever is adapted to move a cam member forming a part thereof intoengagement with a control bell-crank to operate the same to simultaneously cause retraction of a coin retainlng member on said bell-crank as a coin e ecting means also on said bell-crank is advanced to discharge the lowermost coin or cows from a stack of coins in a coin tube.

0 It is furthermore an object of this inventlon to construct a change maker having cam operated means-for'retracting a coin retaining mechanism as a coin ejecting mechanism is advanced to eject a coin.

It is an important object of this invention to provide a change maker of simple and effective construction adapted to be conveniently and positively operated to cause spring and roller controlled coin ejecting mechanisms to beadvanced whereby a selected number of coins of selected denominations are adapted to be discharged from coin tubes into a delivery cup atthe outer end of a discharge chute simultaneously with the retraction of coin retaining mechanisms operable bythe same means actuating the coin ejecting mechanisms.

Other and further important objects of this invention will be apparent from the disclosures in the specification'and drawings.

The invention (in a preferred form) is illustrated in the more fully described.

As shown on the drawin s:

The selective change ma e r compr1ses .a pedestal or base 1 having rigidly secured thereon a casing 2. Fastened to the front rality of headed pins or bolts 4 tor removably su porting a coin holdlng unit in p051- tion. The com holding unit embraces a pair of parallel cross-bars 5 having notches 6 in the lower edges to engage over the 131118 4. Integrally formed on the cross bars 5 are a plurality of studs or pro ections 7. Rigidly secured to the studs 1 are a plurality of parallel coin tubes 8 of different sizes for holding stacks of coins 9 of different denominations. Each coin tube 8 has rigidly secured on the lower portion thereof a collar 10 having a discharge coin guide or mouth iece 11 formed thereon to close the bottom thereof.

The coin tube mouth pieces 11 are positioned above an inclined coin discharge apron or plate 12 having a plurality of parallel slots 13 therein. The coin discharge apron 12 forms a part of a coin discharge chute 14 which is mounted within the lower rear portion of the casing 2. Both of the side walls of the casing2 have outlet openings 15 therein. One of the openings 15 is closed by means of a late or door 16 slidable in guide channe s 17 formed on the casin side walls, as illustrated in Figures 4 an 5. The lower end of the discharge chute .l4leads to the opening 15 in the other casing side wall and connects up with an exterior delivery chute or trough 18, the end of which has a discharge opening 19 in the bottom thereof to permit coins to be deposited in a coin cup 20 positioned below the end of said delivery chute 18. The two openings 15 are provided in the casing side walls to permit either a right hand or a left hand coindelivery chute to be provided with the machine. I I

The lower ends of the coin tubes are positioned to permit the base members 10--11 thereon to engage or seat in an inclined table casting or plate 21 provided with recesses or openings 22. The bottom of each tube base member 1011.is provided with a slot '23, the rear end of which opens into a coin outlet opening 24. Secured against the bottom of the table casting 21 and beneath the coin tube base members 1011 is an ejector guide plate 25 having ejector guide slots '26 therein registering with the coin is best illustrated in Figures2 9, 10 and 11. 7

Since the principle of operation and the construction of each of the various ejecting mechanisms is the same, only-one ejecting mechanism will be described.

Pivotally mounted on a rod or pin 28 within the casing 2 is the upper end of an arm 29 having an inwardly directed finger or projection 30 integrally formed intermediate the ends thereof. Also integrally formed on the lower inner edge of the arm 29 is a cam 31. A lever 32 is integrally formed at right angles to the lower front edge of the arm .29 and projects outwardly through a vertical slot 33 provided for the purpose in the lower front wall of the casing 2. A key or button 34 is secured on the outer end of the lever 32 and is provided with a number plate to designate the denomination of the coins 9 in a respective coin tube 8. Provided on the upper surface of thebase 1 is a pair of spaced lugs 35 for supportlng a pin or rod 36., Pivotedldn the pin 36 between the lugs 35 is thej bight portlon of a bell-crank embracingan up'j-T wardly directed long arm 37 and a rearwardly directed short arm- The lofigf bell-cranklarm 37 is provided with alongi tudinal slot 39, Fig. 6 through'which the lever finger 30,.and the cam 31 project, The

inclined surfaceof the cam 31 is in contact with a roller 40 rotatably mounted'bet'ween side flanges of thelongbell-crank.'.arm.' Engaged around the pin 36 are a pair. of. springs 41, one end of each spring resting? on the base 1 while the other"end",hears against the long bell-crank arm37, "as illus-I' trated in Figure 7. The springs41actto return and hold the bel1-crank 37'--3'8?.and

the lever 32 intheir' normal positions.

Pivoted on the end oft-he short bell-crank arm 38 is the lower end of atom retaining arm 42 which: projects upwardly between adjustable slottediguideplates 43 and 44.

r The guide plates 43and 44 are supported longitudinally of the casing 2 upon uprights 45 secured upon the machine base 1. As shown in Figure 4, the platej43 is provided with transverseend slots 46 through which set screws 47 project and thread into, the upper ends of the uprights '45. The slots 46 in the plate 43 permit said plate to be adjusted on said uprights. The guide plate 44 is provided with transverse slots 48 through which .set screws 49 project and Leeaere thread into the guide plate 43. The guide plate 44 is adjustable on the guide plate 43. he upper end of the coin retaining arm 42 is tapered and normally projects upwardly through the slot 13 in the coin discharge apron 12 to the rear of the coin discharge opening 24-27 to prevent the lowermost coin or coins in the coin tube from prematurely sliding rearwardly out of the tube and into the discharge chute 14. Integrally formed near the upper end of the coin retaining arm 42 is an upwardly and forwardly inclined finger or stop 50 which projects beneath the registering guide slots 2326 to prevent coins tipped on edge in the coin tube 8 from falling through said registering slots 23-26 into the casing 2.

Supported in the upper head end of the long bell-crank arm 37 is a pin 51 on which is pivotally engaged the arms 52 of an ejecting member. The ejecting member arms 52 are integrally connected by a cross-piece 53 having a notched upwardly projecting ejector tip 5 integrally formed thereon. To hold the ejector projected upwardly with the ejecting tip or nose 54 projecting through the registering guide slots 2326,

I a spring 55 is coiled around the pin 51. One

end of the spring 55 is engaged under one of the ejector arms 52 while the other end of the spring 55 bears against a flange 56 struck inwardly from the upper end of the long bell-crank arm 37, as illustrated in Figure 13. Rotatably mounted between the ejector arms 52 is a guide roller 57 which in normal position is adapted to run on the under surface of the table guide plate 25 to limit the movementof the ejector tip 54: through the guide slots 23-26.

The ejector keys 3a are numbered1, 2?, 5, 10, 25 and 50 to indicate the denomination of the coins in the various coin tubes 8. The first and second tubes are for pennies, the third tube for nickels, the fourth tube for dimes,' the fifth tube for uarters, and the last tube for half dollars. The second key is numbered 2 to indicate that two pennies can be ejected by one operation of the key 2. The operation of any of the other keys will result in the ejection of a single coin only of the required denomination from the respectivecoin tube.

The operation is as follows:

Coins of different denominations such as ennies, nickels, dimes, quarters and half dollars are manually deposited in the respective coin tubes in stacks with the lowermost coin in each stack resting on the inner surface of the slotted bottom plate of the tube base member 1011 in the position illustrated in Figure 9.

If, when coins are deposited in a coin tube, the lowermost coin should turn edgewise and project into the registering guide slots 2326, said coin would not be permitted to slide through said guide slots into the casing 2, but would be stopped by the stop or finger 50 which normally is positioned with the upper end contacting the plate 25 below the guide slot 26. The coin or coins which have been upturned may then be removed or set flat within the coin tube in stacked order ready to be ejected.

In case there was only one or coins in a tube and the to slide rearwardly charge position, said mitted to fall a very few lower coin started by gravity toward discoin would not be perupon the discharge apron 12 in view of the fact that the upper end of the retaining arm 42 normally is held projected upwardly through the slot 13 of the apron 12 across the end of the coin tube outlet 01 mouth 11, thereby holding said coin in the bottom of the tube against accidental dis charge.

The control spring a1 acts to hold the bellcrank 37-38 and the actuating lever 32 in their normal positions, as illustrated in Figure 2. When the bell-crank is in normal position the coin retaining arm a2 is in the projected position shown in Figure 9, while the ejector control spring 55 acts to hold the ejector tip 54 projected upwardly through the guideslot 26 and into the table guide slot 22. The ejector roller 57 traclrs on the under surface of the guide plate 25 to facili tate movement of the ejector and also serves as a stop to prevent the ejector tip 54 from projecting upwardly too far to engage against the edge of more than one coin. The ejector in the case of the second coin tube from the left side of the machine is ad just/ed to permit the same to engage the two lower coins instead of only the lowermost coin as is the case for the remaining tubes.

With the ejector in normal position, as shown in Figures 2 and 9, the lowermost coin in a coin stack may be positively ejected by depressin the respective button or lrey- 34 thereby orcing the lever 32 to swing downwardly about the pivot point 28. With the above movement of the lever 32 the cam 31 is forced a ainst the bell-cranlr roller 1-0. The bell-cranfi long arm 37 is thus tipped inwardly or rearwardly as the short bellcrank arm 38 is swung downwardly. As the lever 32 is pushed downwardly the projection 3O swings upwardly to act as a stop to limit the rearward throw of the bellcrank. With the rearward movement. of the bell-crank arm 37 against the action of the springs 4-1 the ejector is also forced inwardly with the ejector tip 54: sliding in the guide slots 23-26 to contact the low- -.ermost coin 9 and Slide the same rearwardly from underneath the stack of coins into 1 discharge position. With the throw of the bell-crank the retaining arm 42 on the short bell crank arm 38 is simultaneously retracted from the position shown in Figure 9 to the position illustrated in Figure 10 out of the path of the coin being e ected. When the front edge of the coin reaches the cutout or outlet opening 2427 the coin is permitted to drop through the mouth of the coin tube base member 10-11 upon thev discharge apron 12. The apron 12 is inclined to permit the ejected coin to slide downwardly by gravity into the chute 14. From the chute 14 the coin passes out of the easing into the exterior chute 18 and finally drops through the opening 19 into the coin cup 20.

Simultaneous with the discharge of a coin the stack of coins tends to drop in the coin tube and rest upon and depress the ejector tip 54, as illustrated in Figure 11, compress:

swing the ejector upwardly into normal po-- sition, as shown in Figure 9, in place to permit e ection of the next coin upon the next operation of the lever 32.

Any combination of change may be rapidly made by simultaneously depressing a selective number of the ejecting keys 34. The various ejector mechanisms may e operated independently'or collectively as desired.

The coin tubes 8 are all secured to the cross bars 5 to form a unit which may be easily removed from the machine by simply lifting the unit to disengage the notch bars from the supporting pins 4 secured on the up er front casing plate 3.
